Great clean office, however my appointment was a waste of time for myself and the provider as she is a surgeon and that is not what I needed. I was in need of an Endocrinologist, but when I entered my information on Zocdoc, it recommended Dr. Sinclair, so I booked the appointment. She’s very knowledgeable and caring, but it was a waste of time for us all.
